A...the proportion of heads your friend observes is closer to 0.5
Answer:
(a) 8 balls
(b) 4 balls
Step-by-step explanation:
Let
Number of balls
For a box, the probability that there are N balls in it is:
For 2 boxes, it is:
From the question, we have:
Favorable outcome
To solve for N, we have:
Divide both sides by 2
Take log of both sides
Apply law of logarithm
Make N the subject
Approximate
Solving (b): Balls in one of the two boxes.
Here, we assume that each ball will have almost the same number of balls at a given instance;
Hence, we have:
<em>4 balls in each box</em>
Answer:
y=45+x
y=2x+15
x=30
Step-by-step explanation:
The problem says that line TQ is 18 units. The little red line through TQ and TR means that both lines are the same, so TR also equal 18 units.
We can solve for x in the equation for TR :
2x+10 = 18
Subtract 10 from each side:
2x = 8
Divide both sides by 2:
x = 4
Because TQ and TR are identical, RS and QS are also identical so we can replace X with 4 in the equation for QS:
9(4) -11 = 36 - 11 = 25
RS = 25 units.
